[Range] | 1 ≤ n ≤ 2, 49 ≤ n ≤ 50 |
|
|
[Description] Transmits the status specified by n as, follows:
nFunction
1, 49 | Transmits paper sensor status (same as ESC v) |
|
|
2, 50 | Transmits drawer |
|
|
[Notes] | • When DTR/DSR control is selected, the printer transmits only 1 |
byte after confirming the host is ready to receive data (DSR signal is SPACE). If the host computer is not ready to receive data (DSR signal is MARK), the printer waits until the host is ready.
When XON/XOFF control is selected, the printer transmits only 1 byte without confirming the condition of the DSR signal.
•This command is executed when the data in the receive buffer is developed. Therefore, there may be a time lag between receiving this command and transmitting the status, depending on the receive buffer status.
•When Auto Status Back (ASB) is enabled using GS a, the status transmitted by GS r and the ASB status must be differentiated.
•The status types to be transmitted are shown below:
